Benefits to the environment and animal welfare are also significant, he says. Erosion is a big problem in the Bay of Plenty and stock shelter belts have become an obsolete concept.
Summerhill Farm forest manager Gabrielle Walton says about 10 per cent of the family farm in Papamoa Hills is planted in trees.
They are harvesting and have achieved higher returns off poorer country than would have been gained off sheep and beef, she says.
"There are a lot of opportunities to plant more trees for a variety of reasons and timber is definitely the most financial one. But they provide shade and shelter for stock, erosion control and riparian management."
There is a lack of planting going on in the region, she says. "Our tree planting started because it is the poorer country or it is prone to erosion with very difficult areas to farm with sheep and beef. So we've slowly put a lot of that into a mixture of species.
"Pines are our cash crop but we're diversifying into alternatives because we think it's good to have your eggs in more than one basket."
Cypress, Tasmanian blackwood and eucalyptus are among the species grown.
Being close to the port of Tauranga is an advantage, she says. "We have got the best timber export port in the country so it's crazy not to be using that."
